[PATCH] s390: lcs driver bug fixes and improvements [1/2]

	Several problems occured with lcs device driver:
	 - device not operational anymore after cable pull/plug-in.
       	 - unpredictable results occured, e.g. kernel panic
	   using cards of type QD8F.
	 - STOPLAN and delete multicast address command
           were not proper recognized by OSA card under heavy network workload.
       	 - channel/device error checks missing in interrupt handler.
	To fix all problems at once recovery of lcs devices has been improved.
	missing error checks in lcs interrupt handler has been added.
	Once a hardware problem occurs lcs will recover the device now properly.
